purpose of this experiment was to test different solute concentrations on the rate of osmosis. Artificial cells were filled with different solute concentrations and placed in water and weighed at equal time intervals to show how the water moves across cell membranes and down its concentration gradient into the lower concentrated area. The weights of the cells were recorded each interval, and then the rate of osmosis was found by calculating the corrected cumulative change in weight. The prediction...

investigation how sugar solutions of different concentrations affect osmosis. Research Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution to one of a higher concentration. If a solution has a low concentration then the amount of (in the case of my investigation) sugar, the solute, will be low and the solution will be weak. If there is high amount of sugar then the solution will be concentrated (have a high concentration). When two solutions are divided...

Lab 1 7.2 Osmosis Introduction Osmosis is the diffusion of water across a selectively permeable membrane in response to a differing overall solute concentration (Starr, Evers, and Starr 85). Most polar molecules such as sugars and proteins cannot freely pass through a lipid membrane; although water molecules are polar they are small enough to pass though the membrane freely. This special case of diffusion that involves the movement of water molecules across a membrane is called Osmosis. This process...

Introduction The movement of water molecules across a semi-permeable membrane is the process of osmosis. If there is a solute and a solvent, each containing different concentration levels, then the water would move along its concentration gradient until each side of the membrane are equal. The water moves because the membrane is impermeable to the solute and the solute concentrations may differ on either side of the membrane. Water molecules may move in and out of the cell, but there is no net diffusion...
